Arduino IDE always over writes the fuse values when it writes a new bootloader. At the time when I used the IDE to upload the correct binaries - after the bad flash - it just left all the fuses at value 0xFF. The Sanguino boards.txt file defines the fuses it will use I just found, the fuses are defined in the Makefile, I thought maybe the precompiled binaries (like: optiboot_atmega1284p.hex) stby vinibali - Sanguino(lolu)
These values are coming from the reprap Mezli page, these should be accurate. Unfortunately I didn't have a single line backup from the previous sessions, where I used to execute avrdude to figure out what would be the original fuse settings. I asked the FB community for this printer. Do you think the bootloader settings can overwrite the fuses which are burned into the empty controller? Thanksby vinibali - Sanguino(lolu)
Hello there! I have a Trony P802 which was working fine with the factory shipped Reprap 0.91 and with Marlin 1.1.9 which was compiled and uploaded by me. Both versions worked fine, until I made some changes in the source files, recompiled it and unfortunately I uploaded the wrong binary without the bootloader. After that, I successfully reuploaded the working binary with the bootloader, but theby vinibali - Sanguino(lolu)
